<div class="textblock"><p>enumeration that determines the way in which two material properties will be combined to yield a friction or restitution coefficient for a collision. </p>
<p>When two actors come in contact with each other, they each have materials with various coefficients, but we only need a single set of coefficients for the pair.</p>
<p>Physics doesn't have any inherent combinations because the coefficients are determined empirically on a case by case basis. However, simulating this with a pairwise lookup table is often impractical.</p>
<p>For this reason the following combine behaviors are available:</p>
<p>eAVERAGE eMIN eMULTIPLY eMAX</p>
<p>The effective combine mode for the pair is maximum(material0.combineMode, material1.combineMode).</p>
